Globe Wernicke Metal 11 drawer cabinet

I am looking to find the value of this metal cabinet I have.  It has 9 drawers at the top of the cabinet that are card file size (currently I store photographs in them).  The bottom section has 2 file drawers which accommodate hanging files or standing files.  It has never been refinished and does have some scratches and marks on it from actual use.  It has six stacking sections which include; the bottom section with the feet, the next section with the file cabinets, the next three sections each have 3 card file drawers in each section and the final section is the actual top of the cabinet.  I am not sure how much it weighs, but we have always moved it in sections because of the weight.  The drawer label holders and drawer pulls are brass.
